IMPROVEMENT IN CULTIVATORS.

Specification forming art of Letters Patent Nb; 115,459, dated May 30,1871.

j I, CONRAD FURs'r,of the city of Chicago, in the county of, Cook andState of Illinois,

have invented certainnew and useful Improvements in Cultivators, ofwhich the following is a full description, reference being had to theaccompanying drawing making a part of this specification, in which-Figure 1 is a perspective view; Fig. 2, a

top view of the frame; and Fig. 3, a longitudinal vertical section online a; y of Fig. 2.

y The nature ofmy invention consists in making the draft-rods, to whichthe plow-beams are attached, adjustable; in so constructing constructionand operation of the same.

In the. drawing,,A represents the curved and bent frame; B, the tongue;0, the axles; D, the wheels; E, F, and G, beams, plows, and handles ofordinary construction; H, the double-tree; I, the whiffletrees; J, bentrods or draw-bars; K, clips for securing the frame to the axles; a,screw-nuts for adjusting theupper ends of the rods J ;j b, stops orshoulders; 0, clips or clamps for adjusting and securing thelower endsof therods J; 0, braces;

f, a bent bar or clevis for attachinga double tree. The frame A isconstructed from a single piece of wrought-iron and bent in theformshown. By making it of this form it answersall the purposes of abent axle, and does not require bracing. This frame is secured to theshort axles G by clips K, and the ends of the frame" project behind suchshort axles. Thewheels D are made in the usual form. The tongue B ismade a of two pieces brought together at the front; ends and separatedat the rear, as shown at Fig.1. The whiffletree and double-tree]; H aremade and attached in any ordinary manner. The rods J J are adjustable,and the beams E are attached to them. The ends of these rods are bent,and

these bent ends are fastened-to the frame A, both at their upper andlowerends, by means of clips or eyebolts a andnuts, or in any othersuitable manner. At their upper. ends the bolt used to i connect theframe and tongue- J in place. The bent ends of the bars J, to which thebeams E-are attached, are made longer than the other ends, making thespace between the frame A and bars J greater at the lower than at theupper ends, to furnish a place for the attachment of the beams. At

their upper ends these bars J are provided with a nut, a. By this nutthe space between the bars J can be adjusted at'any required distance.To the upper and lower sides of the front ends of the beams E plates kare fastened. These plates extend beyond the ends of the beams asufficient distance to allow of the insertion of a small wheel, d,be-

tween them, leaving space enough between the endof the beam and thiswheel to allow the lower end of the bars J to pass through and fastenthe beams to the ends of theframe. The ends of the beams should bechamfered off, or the plates bent down, so as to fit the hitchingrods Jand prevent the rocking of y 'the beams. This wheel (1 is placed betweenthe plates 70 to allow an easy lateral movement of the beams E upon thebars J. It is important that the beams should not rock, as it isdesirable to run close to the plants, and this cannot be done withsafety unless the plows are held in their vertical position. The stopsor shoulders b are made apart of or permanently attached to the rods J,so that, when the space between the beams is adjusted, the space betweenthe rods is also adjusted, as adjusting the space between thehitching-rods adjusts the beams. This is easily done by loosening theeyebolts c and placing the hitching-rods J in position, and thentightening said bolts. The upper end may be adjusted to the screw-nut a.g are bent rods, attachedto both sides of the split tongue B at the rearend to receive thehooks h fastened in the beams E to hold the beams andshovels clear from the ground when the cultivator is moved from place toplace. j are hooks made to slide on so that, when the plows are movedlaterally, they shall not be lifted out of the ground. The chains '0 arefastened to the beams E by a staple, and

in this way the pitch of the beams can be ad-' justed.

Cultivators have heretofore been made with the beams so attached to thebars or frame as to be adjustable; but the bars were immovable, andalways remained at the same distance apart; and in cultivating largecorn the inner ends of these bars are likely to strike the stalks andbreak them, causing considerable damage; but by making the bars Jadjustable this objection is wholly obviated, the bars being movablewith the beams.

In the drawing, the bars J and beams E are shown in position forcultivating large corn; but for cultivating small corn the distancebetween the beams should be less than that shown, which is readilyaccomplished by brin 5; ing the bars J nearer together. I

What I claim as new is 1. The frame A, constructed as described, andextending back of the axles, when so combined with the short axles (Jthat the ends of the plow-beams may be raised and lowered, substantiallyas and for the purposes specified.

2. The adjustable bars J, when combined with the frame and plow-beams soas to move with the beams E, substantially as described.
